As shown in theillustrations both SSRs have a square shape with rounded corners; both units have thesame physical thickness (approximately 2”). The 18” unit weighs approximately 14.5pounds; the 12” unit approximately 8 pounds. The 2” wide edge of both units contain4 deep grooves separated by fins; this structure is an important electrical feature andmust be keep free of extraneous material. Likewise, the central 8” square area oneach face is electrically active and must be kept free of contaminating materials.Take special note that each face of the SSR has a unique electrical function and mustproperly oriented in operation (see section 2.0). The illustrations show the SSRwithout the radomes normally attached to each face. When attached the radome withthe Andrew flash indicates which side should be facing the handset (mobile unit).1.2 Electronic Description & Block DiagramThe 1900 series PCS repeaters operate in the 1900 MHz PCS band. They weredeveloped to provide more reliable coverage and/or range extension of PCS systemswithin sheltered structures. Specific models for each of the major US PCS sub-bands
( A, B, C, D, E & F) are offered. Pre-aligned antennas on each side of the repeatersmake them easy to install and simple to operate. Designed for indoor environments,they only require a standard US 110VAC outlet for operating power. All threepopular PCS systems (TDMA, CDMA & GSM) are supported.Figure 3 is an electronic block diagram of SSR internal and external circuitry.Separate antennas provide receive and transmit functions for the complementaryuplink and downlink bands. In operation, the appropriate receive antenna feeds its’signal to a band pass filter that functions to reject undesired signals and isolate thecomplementary band’s signal. The signal from the band pass filter feeds an amplifierwith an AGC loop that limits maximum output power to approximately 100milliwatts. The amplifier output feeds a second band pass filter functioning to limitspurious amplifier output signals and further isolate the complementary band’s signal.The complementary band’s signal path is identical to that previously described,except in the reverse direction. Both amplifiers include crude RSSI circuitry andover-current protection circuitry.1.3 Operational EnvironmentThe SSR has been designed to operate properly in a temperature and humiditycontrolled indoor environment. Operation in environments where the ambienttemperature is outside the 50o-85o F range or the relative humidity is greater than 50%may result in unsatisfactory performance. Exposure to temperatures outside the 10o-120o F range or relative humidity greater than 80% may result in permanent damageto the unit.2.0 Installation Guide Lines2.1 LocationCAUTION: In order to comply with FCC rules for rf exposure, the following mustbe observed:The antenna must be installed such that a minimum separation distance of 20 cm. ismaintained between the antenna and any persons.Proper operation of the SSR cannot be achieved if the following installation locationguide lines are not followed.The prevention of signal feedback from the transmit antenna on one side of the SSRto the same path’s receive antenna on the opposite side of the SSR is paramount toproper operation of the SSR. Any matter in the surrounding environment of the SSRwill produce undesirable feedback signals. Any object with any physical dimensionthat is greater than 2 inches may cause undesirable signal reflections and/orrefractions severe enough to cause unstable operation of the SSR. Metal objectsnormally cause worse reflections and/or refraction than non-metallic objects. Thelevel of undesired reflected and/or refracted signals is directly proportional to the sizeof the object and inversely proportional to the distance between the SSR and the
